Question

Suppose that the address of the jump instruction (j) is 0x2000,0000. Is it possible to use this jump instruction to set the PC to the address as 0x3000,0000? Please elaborate your answer

Answer 1

1). ANSWER :

GIVENTHAT :

In MIPS, jump instruction is used to move from one address to another but with a condition that difference between the current address and the address to which you want to jump should not be greater than 2²⁸

We have:

Current address = 0x20000000

New Address = 0x30000000

let us see the difference betwen the two:

0x30000000 - 0x20000000 = 0x10000000

in binary, we can write it as

0001 0000 0000 0000 0000 0000 0000 0000 = 2²⁸

But it must be less than 2²⁸

So, we can not use jump instruction for given addresses
